I realize you posted this a while ago and may have even delivered already, but I wanted to say Hi! and I live in Guam also. I'm on the military base but I have a good friend who is a local here, who got exemptions for her DD and has so far delayed all vaccinations. She is a fellow MDCer, her name is Freelove, you may want to PM her with your questions.
I hope you are enjoying Guam!
